I will not take into account other platforms, but on X11 powered ones a theme that-want-to-be-transparent can relay on composite managers that are pretty standard these days. The client side (toolkit) should only provide ARGB windows. ...which makes it a nice whish-item for the next version :) -- Sanel _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
